Electronic parking brake system
warning

CAUTION

If the brake system warning light
turns on, the electronic parking
brake system may be malfunction-
ing. Immediately stop your vehicle in
the nearest safe location and con-
tact your SUBARU dealer.

If a malfunction occurs in the electronic
parking brake system, the brake system
warning light turns on. Refer to “Electronic
parking brake light” FP180.

Parking tips

When parking your vehicle, always per-
form the following items.
.

Apply the parking brake firmly.

Put the select lever in the “P” position.

Never rely on the mechanical friction of the
transmission alone to hold the vehicle.

When parking on a hill, always turn the
steering wheel. When the vehicle is
headed up the hill, the front wheels should
be turned away from the curb.

When facing downhill, the front wheels
should be turned into the curb.

WARNING

Never leave unattended children

or pets in the vehicle. They could
accidentally injure themselves or
others through inadvertent op-
eration of the vehicle. Also, on
hot or sunny days, the tempera-
ture in a closed vehicle could
quickly become high enough to
cause severe or possibly fatal
injuries to people.

Do not park the vehicle over

flammable materials such as dry
grass, waste paper or rags, as
they may burn easily if they come
near hot engine or exhaust sys-
tem parts.

Be sure to stop the engine if you

take a nap in the vehicle. If engine
exhaust gas enters the passen-
ger compartment, occupants in
the vehicle could die from carbon
monoxide (CO) contained in the
exhaust gas.

CAUTION

If your vehicle has a bumper

under guard (optional), pay atten-
tion to blocks and other obstruc-
tions on the ground when park-
ing. The underspoiler could be
damaged by contact with them.

The braking power of the parking

brake may not be sufficient when
s t r o n g e r b r a k i n g p o w e r i s
needed (e.g., when parking on a
steep slope while towing a trai-
ler).

7-16. Hill start assist system

WARNING

The Hill start assist system is a

device only for helping the driver
to START the vehicle on an uphill
grade. To prevent accidents
when the vehicle is parked on a
slope, be sure to firmly set the
parking brake. When setting the
parking brake, make sure that the
vehicle remains stationary when
the brake pedal is released.

Do not turn the ignition switch to

the “LOCK”/“OFF” position while
the Hill start assist system is
operating. The Hill start assist
system will be deactivated and
may lead to an accident.

The Hill start assist system is a device to
make the following vehicle operations
easier.

Starting forward facing uphill

Starting backward facing downhill

Brake pedal

When the vehicle has stopped with the
brake pedal depressed, the Hill start assist
system operates under the following con-

Hill start assist system

354

(357,1)

北米Model "A3200BE-A" EDITED: 2018/ 3/ 5

ditions.
Braking power is maintained temporarily
(for approximately 2 seconds) by the Hill
start assist system after the brake pedal is
released. The driver is therefore able to
start the vehicle in the same way as on a
level grade, just using the accelerator
pedal.

If the braking power of the Hill start assist
system is insufficient after the brake pedal
is released, apply more braking power by
depressing the brake pedal again.

The Hill start assist system may not
operate on slight grades. Also, the Hill
start assist system does not operate in the
following cases.

When starting backward facing uphill

When starting forward facing downhill

While the parking brake is applied

While the ignition switch is in the “ACC”

or “LOCK”/“OFF” position

When using the Hill start assist system, a

braking effect may be felt even after the
brake pedal has been released.

CAUTION

The braking power of the Hill start
assist system may not be sufficient
when strong braking power is
needed (e.g., when towing a trailer).

NOTE

A slight jolt may be felt when the
vehicle begins to move forward after
being reversed.

7-17. BSD/RCTA (if equipped)

The BSD/RCTA consists of rear radar with
Blind Spot Detection and Rear Cross
Traffic Alert.

These functions enable the system to
detect objects or vehicles to the rear,
drawing attention to the driver when
changing a lane or when driving in reverse.

WARNING

The driver is responsible for driving
safely. Always be sure to check the
surroundings when changing lanes
or reversing the vehicle.

The system is designed to assist the
driver to change lanes or reverse
safely by monitoring the rear and
side areas of the vehicle. However,
you cannot rely on this system alone
in assuring the safety during a lane
change or reversing. Overconfi-
dence in this system could result in
an accident and lead to serious
injury or death. Since the system
operation has various limitations,
the flashing or illumination of the
BSD/RCTA approach indicator light
may be delayed or it may not operate
at all even when a vehicle is present

in a neighboring lane or approach-
ing from either side.

The driver is responsible for paying
attention to the rear and side areas
of the vehicle.

System features

BSD/RCTA consists of the following func-
tions.
.

To detect a vehicle in a blind spot on an

adjacent lane or a vehicle approaching at
high speeds (Blind Spot Detection)
.

To detect a vehicle approaching from

the right or left while reversing the vehicle
(Rear Cross Traffic Alert)

The system uses radar sensors for the
above functions.

NOTE

The BSD/RCTA radar sensor has been
certified by the radio wave related laws
of the U.S. and Canada. When driving in
other countries, certification of the
country where the vehicle is driven
must be obtained. For certification in
the U.S. and Canada, refer to “Certifica-
tion for the BSD/RCTA” FP363.

Blind Spot Detection (BSD)

Operating range

The system warns the driver of dangers as
follows.
.

If the system detects a vehicle in the

blind spot, the BSD/RCTA approach in-
dicator light(s) on the outside mirror(s) will
illuminate.

If the driver operates the turn signal

lever in the direction which the BSD/RCTA
approach indicator light is illuminating, the
corresponding BSD/RCTA approach indi-
cator light will flash.

Rear Cross Traffic Alert (RCTA)

Operating range

The system notifies the driver of another
vehicle approaching from either side when
driving in reverse. This feature helps the
driver check the rear and side areas of the
vehicle when moving backward.

If the system detects a vehicle approach-
ing from either side while moving back-
ward, it warns the driver of dangers in the
following way.
.

The BSD/RCTA approach indicator

the radar may not reflect (vehicles

with a low body height such as
sports cars or a trailer with no
cargo)
– Vehicles that are not approaching
your vehicle even though they are in
the detection area (either on a
neighboring lane to the rear or be-
side your vehicle when reversing)
(The system determines the pre-
sence of approaching vehicles
based on data detected by the radar
sensors.)
– Vehicles traveling at significantly
different speeds
– Vehicles driving parallel to your
vehicle at almost the same speed
for a prolonged time
– Oncoming vehicles
– Vehicles in a lane beyond the
neighboring lane
– Vehicles travelling at a signifi-
cantly lower speed that you are
trying to overtake

On a road with extremely narrow

lanes, the system may detect vehicles
driving in a lane next to the neighboring
lane.

7-18. Reverse Automatic
Braking System (if equipped)

Reverse Automatic Braking is a system
designed to help avoid collisions or reduce
collision damage when reversing the
vehicle. If a wall or an obstacle is detected
in the reversing direction, the system will
notify the driver with a warning sound and
may activate the vehicle’s brakes auto-
matically.

WARNING

Reverse Automatic Braking is not

a system intended to replace the
driver’s responsibility to check
surrounding areas for vehicles or
obstacles to avoid a collision.

The driver is responsible for driv-

ing safely. Always be sure to
check the surroundings visually
when reversing the vehicle.

There are some cases in which

the vehicle cannot avoid colli-
sion, because the system opera-
tion has limitations. The warning
sound or automatic braking may
be delayed or may not operate at
all even when an obstacle is
present.

Reverse Automatic Braking System

364

(367,1)

北米Model "A3200BE-A" EDITED: 2018/ 3/ 5

The system is not designed to

detect people (including chil-
dren), animals or other moving
objects.

Depending on the vehicle condi-

tion or the surrounding environ-
ment, the sonar sensor’s ability
to detect objects may be compro-
mised.

NOTE

The Reverse Automatic Braking Sys-
tem records and stores the following
data when automatic braking operates.
It does not record conversations, per-
sonal information or other audio data.
.

Distance from the object

Vehicle speed

Accelerator pedal operation status

Brake pedal operation status

Select lever position

Outside temperature

SUBARU and third parties contracted
by SUBARU may acquire and use the
recorded data for the purpose of vehi-
c l e r e s e a r c h a n d d e v e l o p m e n t .
SUBARU and third parties contracted
by SUBARU will not disclose or provide

the acquired data to any other third
party except under the following con-
ditions.
.

The vehicle owner has given his/her

consent.
.

The disclosure/provision is based

on a court order or other legally en-
forceable request.
.

Data that has been modified so that

the user and vehicle cannot be identi-
fied is provided to a research institution
for statistical processing or similar
purposes.

Reverse Automatic Braking
System overview

The system detects objects using sonar
sensors installed in the rear bumper.
.

If the system determines a possible

collision with an object in the reversing
direction, automatic deceleration will be
activated. Also, beeping sounds will acti-
vate.
.

If the vehicle is further reversed, auto-

matic hard braking will be applied and a
continuous beeping sound will activate.

Detecting range

Detecting range (width): Approximately 6
in (15 cm) outside of the vehicle width

Range that the system cannot detect:
Approximately 20 in (50 cm) behind the
rear of the vehicle

Detecting range (length): Approximately
5 ft (1.5 m) from the rear of the vehicle

WARNING

If your vehicle is trapped on a rail-
road crossing and you are trying to
escape by reversing through the
crossing gate, the system may re-
cognize the crossing gate as an
obstacle and the brake may activate.
